iOS客户端的安装和升级—针对ADHoc证书

这篇文章纯给自己留个备份，所以对AdHoc证书内部分发和对iOS客户端开发不知道的请直接无视。

一般在iOS游戏或应用研发过程中，正式公布到App Store之前，都应该内部的检测，客户端的调试是个不大不小的难题。苹果提供了AdHoc的证书（普通版可以装100台设备，企业版无限），登记设备号 的就能借助iTunes或者无线网络调试使用AdHoc证书的App。具体不多赘述。

之前有用过一款产品叫HockeyApp（），帮助推动内部的分发和调试，支持安装、检测升级，非常便捷，简单剖析了一下其原理：

1. 服务端提供API供客户端获取最近版本信息，参考如下：

;udid=d2134514a9c016fbd016a0815f1b3f41d9f38c82&sdk=HockeySDK&sdk_version=2.5.4b1&uuid=87dcb0e9981f34f6ad998590087fc554&app_version=4.2.0.12100902&os=iOS&os_version=6.0&device=iPhone3%2C1&lang=zh-Hans&first_start_at=10%2F09%2F2012&usage_time=27300

2. 客户端根据版本列表判断是不是最新版本，和是不是要强制升级，如果必须更新，可以类似与HockeyAPP内嵌一个网页显示版本信息，点击升级图标后，访问服务端的下载升级包的API。

网页更新链接代码如下：

<a href="itms-services://?action=download-manifest&url=https://sdk.hockeyapp.net/api/2/apps/565b9262a3913bb1123c71ba6575e07b?format=plist&udid=d2134514a9c016fbd016a0815f1b3f41d9f38c82">Tap Here to Update</a>

3. 服务端提供下载升级包的API，传入用户设备号和请求的版本号参数，返回一个manifest.plist文件，本质是一个XMLadhoc证书，包含升级包描述信息，参考如下：

;udid=d2134514a9c016fbd016a0815f1b3f41d9f38c82

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

<key>items</key>

<array>

<dict>

<key>assets</key>

<array>

<dict>

<key>kind</key>

<string>software-package</string>

<key>url</key>

<string>;amp;udid=d2134514a9c016fbd016a0815f1b3f41d9f38c82</string>

</dict>

<dict>

<key>kind</key>

<string>display-image</string>

<key>needs-shine</key>

<false />

<key>url</key>

<string>;amp;udid=d2134514a9c016fbd016a0815f1b3f41d9f38c82</string>

</dict>

</array>

<key>metadata</key>

<dict>

<key>bundle-identifier</key>

<string>com.idfsoft.idfCity</string>

<key>bundle-version</key>

<string>4.2.1.12101102</string>

<key>subtitle</key>

<string>4.2.1 (4.2.1.12101102)</string>

<key>title</key>

<string>Metal Nation</string>

<key>kind</key>

<string>software</string>

</dict>

</dict>

</array>

</dict>

</plist>

其中software-package对应的Url为ipa文件下载地址，其中display-image对应的Url为App的图标图片URL

5. 后台管理中adhoc证书，需要提高页面让客户可以上传最新的ipa文件和输入版本升级信息，其中ipa文件的详解逻辑如下：

基本上就这样。
